The fan 14 can be connected and fixed to the filter plate 15 using a cable tie or a detachable connector, so as to facilitate replacement or maintenance of the fan.

[0039] Furthermore, an air inlet 7 is provided on the outside of the base 4, and the air inlet 7 is arranged below the filter plate 15. A plurality of air inlets 7 are provided, and the plurality of air inlets 7 are arranged equidistantly. The air inlets can be provided on multiple sides of the base 4. After the fan 14 is started, during the gas flow, the air flow enters the base 4 from the air inlet 7, and is then transported to each air distribution plate 8 from the air duct 12.

[0040] Furthermore, a rotating shaft 17 is fixedly installed at the output end of the middle fan 14, and the rotating shaft 17 penetrates the filter plate 15. A scraper 16 is fixedly installed on the outer side of the rotating shaft 17. There are multiple scrapers 16, and the multiple scrapers 16 are arranged in an array. The scraper 16 fits the filter plate 15. The storage box 5 is slidably installed on the outer side of the base 4, and the handle 6 is fixedly installed on the outer side of the storage box 5. The middle fan 14 refers to the fan located at the geometric center of the filter plate 15. The synchronous rotation of the middle fan 14 and the scraper 16 is achieved by the rotating shaft 17. The two ends of the rotating shaft 17 are respectively connected to the blades of the fan 14 and the scraper 16. The scraper 16 and the blades of the fan are synchronously rotated. The scrapers are arranged in an array along the circumference of the rotating shaft 17. The length of the scraper 16 does not exceed the edge of the filter plate 15. As the scraper 16 rotates, the scraper 16 will not interfere with other parts in the device. Bristles are distributed on one end of the scraper 16 facing the filter plate 15 , and the bristles are in contact with the bottom surface of the filter plate 15 . As the fan rotates, the bristles clean the filter plate 15 to prevent dust from accumulating on the filter plate 15 .

[0041] Furthermore, an air distribution hole 9 is provided on the outside of the air distribution plate 8, and a plurality of air distribution holes 9 are provided, and the plurality of air distribution holes 9 are arranged equidistantly. The air distribution plate 8 is a shell-like structure transversely fixed on the back plate of the box body 1, and the plurality of air distribution holes are transversely equidistantly arranged on the air distribution plate 8, and the plurality of air distribution holes can evenly deliver the airflow formed by the fan 14 into the box body 1, and evenly dissipate heat for each inverter body.

[0042] Furthermore, an air outlet 20 is provided below the heat dissipation box 2, the heat dissipation box 2 is connected to the box body 1, a second rotating shaft 21 is rotatably installed at the connection position between the heat dissipation box 2 and the box body 1, and a baffle 18 is fixedly installed above the second rotating shaft 21. The air outlet 20 is a long strip structure, extending along the length direction of the heat dissipation box 2, and is used to dissipate the hot air in the box body 1 to the outside. When the airflow in the box body changes, the baffle 18 will rotate around the second rotating shaft 21 to open or close.

[0043] Furthermore, a spring spring 13 is fixedly installed on the outside of the heat dissipation box 2, and the output end of the spring spring 13 is fixedly connected to the second rotating shaft 21. A limit plate 19 is fixedly installed inside the heat dissipation box 2, and the limit plate 19 is at a 45-degree angle. When the baffle 18 is closed, the spring spring 13 is in the original length state. When the baffle 18 is opened, the spring spring 13 is compressed or stretched. After the airflow in the box body 1 tends to be stable, the spring spring 13 returns to the initial state, the baffle 18 is reset and closed, and the heat dissipation box stops dissipating heat to the outside. That is, the operation of the heat dissipation box 2 is synchronized with the operation of the internal fan 14, and is also synchronized with the start and stop of each inverter body. When the inverter body stops working, the internal fan 14 stops working, the airflow in the box body 1 stops flowing, and the baffle 18 is closed to prevent external mosquitoes from crawling into the box body 1 from the air outlet of the heat dissipation box 2, thereby protecting the inverter body and related components and circuits in the box body.

[0044] The limit plate is tiltedly arranged at one end of the baffle 18 away from the second rotating shaft 21, and is used to limit the baffle 18. The length of the baffle 18 is the same as the length of the opening opened on the side wall of the box body 1. When the network communication frequency conversion device is not working, the baffle 18 is closed on the side wall of the box body 1, and the box body 1 and the heat dissipation box 2 are not connected. The limit plate 19 is connected to the opening opened on the side wall of the box body 1 through an angle code, so that the limit plate 19 is fixed at the opening opened on the side wall of the box body 1 and forms a 45-degree angle therewith. The length of the limit plate 19 can be the same as the length of the baffle 18, or the length of the limit plate 19 can be shorter than the length of the baffle 18, and the limit plate 19 can limit the extent of the baffle 18. When the airflow in the box 1 changes, a small change in the airflow easily pushes the baffle 18 to rotate around the second rotating shaft 21, so that the baffle 18 opens. After the baffle 18 opens to a certain extent, it is limited by the limit plate 19 to maintain its opening degree and facilitate the reset of the baffle 18. The limit plate 19 can well control the opening degree of the baffle 18, and prevent the baffle 18 from opening too much under the action of the airflow, thereby causing the problem of failure of the clockwork spring 13 or difficulty in resetting.

[0045] Furthermore, the mounting base 10 includes a base 22, which is C-shaped. A buffer spring 23 is fixedly installed on the inner side of the base 22. There are multiple buffer springs 23, which are arranged equidistantly. A pressure plate 24 is fixedly installed on the other end of the buffer spring 23, and the mounting plate 11 is arranged between the pressure plates 24.

[0046] Working principle:

[0047] First, when in use, the fan 14 circuit is started. The fan 14 is started so that air flows in from the air inlet 7, passes through the filter plate 15 into the air duct 12, and then passes through the air duct 12 into the air distribution plate 8. The air distribution plate 8 is provided with air distribution holes 9 on the outside. The air distribution holes 9 are evenly arranged so that air flows into the box 1 evenly, cools down the inverter body on the mounting plate 11, avoids insufficient heat dissipation, and improves the working efficiency of the inverter body.

[0048] Secondly, during the rotation of the fan 14, the fan 14 in the middle drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the scraper 16 to rotate. During the rotation of the scraper 16 arranged in an array, the dust accumulated on the surface of the filter screen is scraped off, thereby preventing the filter plate 15 from being blocked, further improving the working efficiency of the inverter body, and by providing the storage box 5, the storage box 5 can collect dust for easy cleaning;

[0049] Finally, when the airflow enters the box body 1 evenly, the air pressure in the box body 1 increases, and the air pressure pushes the baffle 18, and the baffle 18 drives the second shaft 21 to rotate, so that the airflow in the box body 1 is discharged through the air outlet 20. The baffle 18 can be limited by setting the limit plate 19. By setting the spring spring 13, after the fan 14 is turned off, the spring spring 13 drives the second shaft 21 to reset, thereby improving the air tightness of the box body 1, preventing dust from entering the box body 1 through the air outlet 20, improving the dustproof performance of the box body 1, and ensuring the working efficiency of the inverter body.

[0050] The fan 14 circuit is started. The fan 14 is started so that air flows in from the air inlet 7, passes through the filter plate 15 into the air duct 12, and then passes through the air duct 12 into the air distribution plate 8. The air distribution plate 8 is provided with air distribution holes 9 on the outside. The air distribution holes 9 are evenly arranged so that the air flows into the box 1 evenly.

[0051] During the rotation of the fan 14, the fan 14 in the middle drives the rotating shaft 17 to rotate, and the rotating shaft 17 drives the scraper 16 to rotate. During the rotation of the scraper 16 arranged in an array, the dust accumulated on the surface of the filter screen is scraped off, thereby preventing the filter plate 15 from being blocked;

[0052] The air pressure pushes the baffle 18, and the baffle 18 drives the second shaft 21 to rotate, so that the airflow in the box body 1 is discharged through the air outlet 20. The baffle 18 can be limited by setting the limit plate 19. By setting the clockwork spring 13, after turning off the fan 14, the clockwork spring 13 drives the second shaft 21 to reset, thereby preventing dust from entering the box body 1 through the air outlet 20.

[0053] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of this application, this does not limit the scope of patent protection of this application. All technical solutions generated by replacing or modifying equivalent structures or equivalent processes based on the essential concept of this application using the contents recorded in the specification and drawings of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, are included in the scope of patent protection of this application.
